hi jim,
I think definitely not, if an element has a native mapping to an
accessibility API, why would you want to expose the implict aria role in the
dom? this would have the effect of overriding the native role. if there is a
native accessibility API mapping implemented in the browser you don't need
ARIA unless you as an author want to overide that mapping.
